Abstract

The circular saw blade comprises a steel support disc made from carbon steel and teeth made from a special steel chosen according to its cutting characteristics. The teeth are formed in an arched bar welded onto the edge of the support disc by a laser beam. The machine (30) for making the saw blade comprises a frame (32) carrying a drive motor with a reduction gear. The reduction gear comprises an output shaft (38) on which is mounted the support disc. Two webs (42) fix the disc on the shaft. The bar, whose length corresponds to the support disc circumference is translated by a drive device (44) provided with grooved rollers (46).
